Though the photo set is identified as Beckman with "employees," some of the photographs depict ceremonies and visits to non-corporate locations, like CalTech. Some photographs are attributed, dated (1941, 1962, 1967), or captioned; others lack descriptive information. Identified individuals include Jack Finney, Tony Zerbo, Ray Fletcher, Hal Peper, Ray Carter, and Alvera Oredson.
